No, not specifically for my bipolar disorder. However, I do take a daily multivitamin and occasional iron supplement (during my period) to prevent deficiencies that could reduce my energy levels, or just generally make me feel physically unwell. I did try OTC fish oil a long while back, and took the maximum of the highest potency OTC stuff. It did very little, so I quit it. Instead, I enjoy eating lots of fish (salmon and tuna). That's much more pleasant.

Q: How good is your diet (excluding any supplements)?
